Re: Exit walsender before confirming remote flush in logical replication

Dear Greg, All

I'm interested in walsender shutdown mode option as well. Unexpected waiting for
wal sender shutdown in fast mode creates some problems to follow a SLA. I also
propose to create a GUC which can be used to set the shutdown mode globally.
Once, the original author was not responded for some time, I like the idea to
create a new separate patch for walsender shutdown mode based on the work in
this thread. I'm ready to participate in patch preparation and testing.

With best regards,
Vitaly
